Patent CA-2467953-C (CA)
Inventor: YOON ROE-HOAN
IPC: C02F11/147
Filed: 2002-02-20
Granted: 2010-06-01
Abstract: L'invention concerne des lipides formés naturellement d'origine végétale et animale brisés en petites molécules et utilisés en tant qu'aides à la déshydratation. Ce procédé de rupture des molécules comprend la transestérification, l'interestérification, et la saponification suivie de l'acidulation. Les molécules de lipides modifiées peuvent absorber l'eau à la surface des particules à déshydrater et améliorer considérablement leur hydrophobie, ce qui permettra de faciliter l'augmentation du rapport de déshydratation et, donc, de réduire la moisissure du gâteau. Les lipides modifiés sont des aides à la déshydratation plus efficaces que les lipides non modifiés formés naturellement, probablement parce qu'ils peuvent former plus facilement des monocouches de paquets fermés d'agents hydrophobes à la surface des particules.

Abstract: An apparatus and method for the automated preparation of treated monolayers of sample material, comprising: a centrifuge having a rotor (12) carrying removable chamber blocks (14); sample and reagent dispensers (26) and control systems (20). First, centrifugal force sediments sample material discretely to form a monolayer onto a receiving surface member (32) on one of the chamber blocks (14), while the same centrifugal force opens a valve (48) in the chamber block (14) to drain sample material. Then, centrifugal force delivers sequentially into discrete chamber blocks (14) discrete treating agents, during which time the sampler material monolayer is held in place on the receiving surface member (32) by centrifugal force. Then, each chamber block (14) is drained centrifugally through its already opened valve (48). Each treated sampler material is confined to an individual chamber block (14).  Batch and random access delivery of treating agents can be employed. Each chamber block (14) includes separate inlets for the sample and treating agents.

Abstract: [0104] A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer/catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume dampens spurious exhaust pressure excursions and removes particulates in the exhaust. The second volume houses an oxidation catalyst for treating exhaust to reduce exhaust emissions. The engine oil has at most 10 ppm zinc content to reduce metal poisons contained in the exhaust prior to contact with the oxidation catalyst. The engine oil preferably has a very low ash content to minimize sulfur combustion components in the exhaust to reduce masking of the oxidation catalyst. The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.
